I think there is likely some western chauvinism element to a lot of newer leftists that are not in favor of multipolarity. The propaganda doesn't wash away from the mind so quickly for many. So they have a tendency to think Actual Existing Socialist states are not valid in some way because they have not learned anything beyond the propaganda.
In their minds, this would make multipolarity messy. Better to have a global authority to keep order. And yet they call those in favor of multipolarity authoritarians.
found this via hexbear yesterday, Ukr forces have been thinking about doing something like this for a good while
this article is from last December:
Russia had to arm and feed its forces via three crossings: the Antonovsky Bridge, the Antonovsky railway bridge and the Nova Kakhovka dam, part of a hydroelectric facility with a road running on top of it.
The two bridges were targeted with U.S.-supplied M142 High Mobility Artillery Rocket Systems — or HIMARS launchers, which have a range of 50 miles — and were quickly rendered impassable.
“There were moments when we turned off their supply lines completely, and they still managed to build crossings,” Kovalchuk said. “They managed to replenish ammunition. … It was very difficult.” Kovalchuk considered flooding the river. The Ukrainians, he said, even conducted a test strike with a HIMARS launcher on one of the floodgates at the Nova Kakhovka dam, making three holes in the metal to see if the Dnieper’s water could be raised enough to stymie Russian crossings but not flood nearby villages.
The test was a success, Kovalchuk said, but the step remained a last resort. He held off.
